Thisinvention relates toimprovements in water closets having a seat lid, wherein the .fiushingis effected in such a manner that when the seat lid israised a flushing cistern chamber connected to the closet is filled with the required quantity of 'fiushing water which when the seat lid is turned down streams froln the flushing cistern chamber into the closet bowl. I i

According'to the invention the seat lid is not rigidly connected to any of the members necessary to effect the flushing, but

movable freel about one or more. hinges,

,. and first in aturned-downposition adapted to actuate by its weight the" members effect ing the flushing. I I I As an example, a water closet according to this invention is shown in the accompanying drawings, wherein.

igurel is a vertical section of therear part of the closet, with the flushing c stern chamber and the flushing device. a

Figure 2 shows on a'larger scale a detail in vertical section.

Figure Bis. a vertical section on the line A-A of Figure 2, and Figure 4 is a hori I zontal section on the line -B---B of Figure 2.,

In the upper, rear part of the closet 1 50 there is a chamber 2, the flushing cistern chamber. That wall of the flushing cistern chamber, which is turned towards the closet bowl, is provided with a discharge-hole 3, and adjacentto said hole'there'is aclack valve 4. In the closet there is a verticalv channel 5 formedof china and. open at both ends, and a vertical pipe '6 is secured watere tight to the bottom of the flushing cistern' chamber, the lower-end of said pipe being situated beneath the hammer the flushing cistern chamber 2 and the closet 1. The pipe ,6 forms an open channel which upwards.

,opens above the water level in the flushing cistern chamber When the latter has been filled with the required quantityof water.

The seat of the closet comprises three main parts, viz. the stationary seat member 6* which is attached to the closet, the seat 7 which is screwedto theseatemejmber6 by means of common hinges,-E and the seat lid 8 which is screwed to the stationary seat member 6"- above the seat by means, of a special hinge,

stationary hinge member 9 attached to the lever 30 in such The latter, which is shown on a; larger scale in 'Figures2-4, consists of a member 10- to which the seat lid 8 is screwed,

and ahin'ge shaft 11. The stationary hinge member 9 is provided with a recess 12,Figure 3., for an angledever 13 pivoted about the hinge shaft 11. When the seat lid has been turned down a projection l' ofzthe" angle-lever 13. rests ontheedge of said lid,

so that the lever is held in a raised position.

In the lever 13 there is mounted 'a pivot 15to Which one end'oii' the vrod 16 is Se, cured. The rod 16 extends downwards through the channel 5, and its lower end is threaded into a link 17 which by a pivot 19 slidable in a slot 18 is connected to the lever 20, one end of, which is pivoted to the closet,

by means of'a bolt21. The other end of the lever'20 is by a pivot 23. slidable'in a the loop-screw 27 to the clack .valve 4. The other-end of the arm 26 supports the lever of a float cock when the lever 20 has been raised, the float 29 being attached to said a manner that it may be vertically adjuste I device operates in the .following manner: I 1' I In the initial positionthe turned down seat lid 8 rests on the projection 14- er the angle-lever 13, The lever 13 and the lever t 20 connectedthereto bymeans of the rod 16, are held in a raised position by the weightof the seat lid. .In this raisediposi- 'tion of the lever the supporting arm 26 con-.

nected to said lever Occupies'such a position that the clack valve 4 through the chain 28 is held raised and the lever 30 of the float cock is supported by the arm 26, so thatthe float cock is held closed. I I

By threadingthe rod .16more or less into.

the link 17 and by raising orloWering the loop-screw this initial position and the required ,raisin are easily adjust-ed I i I I I When the closet isto. be used the seat lid 8 is raised, The lever 13 is then liberated, and

the lever 20 I connected thereto is swung. downwards owingto the weight of the lever, and that of the members operating thesame until the bottom of the pipe 25rests on the I g height of the clack valve- 4;

pipe 6. The chain 28 is then slack, and the clack valve 4: closes the discharge-hole 3 of the flushing cistern chamber. The lever 30 of the float cock is now no more supported by the arm 26, and therefore the float secured to the lever 30 opens the c ck owing to its weight. The water now streamsto the flushing cister chamber until the water level therein has raised to such a height that the float has risen and the lever 30'l1as closed the cock. l r l 'When the closet has been used the seat lid 8 is turned down. turned down it actuates the angle-lever 13 by its weight, so that said lever is swung upwardsfcausing the rod 16, the lever 20, the rod 2 1 and the'arm 26 connected thereto to be raised. The clack valve is now raised by the chain 28, so that the flushing water collected in the flushing cistern chamber streams through the discharge-hole 3 into the closet bowl. The raised arm 26 now supports the lever 30 of the float cock again, so that the float cock remains closed.

By displacing the pivots 19 and 2c in the slots 18 and 22 respectively the rods 16 and 24 may be adjusted laterally, the pivots 19 and 23 being then locked again to the lever 20.

Owing to the pipe 25 enclosing the pipe 6, splash arising when filling the flushing cistern chamber is prevented from entering the pipe 6 and thus from streaming down on the floor. Y

As clearly shown inthe drawings, the lid,

at the beginning of its raising movement, has

been disengaged from the lever 13 of the connectlng means, but yet the lever 13 has been swung a little distance from the posi; tion shown in Fig. 2, due to the weight of the members 16, 20, 24; and 26 constituting the connecting means. As soon as the lid raised from its lowermostposition, said weight is able to swing the lever 13 a little. hen the lid is swung downwards after the closet has been used, this movement'hasno action whatever upon the connecting means (the members 13, 16, 20, 24 and 26) until the lid at the end of its downward movement strikes against the lever 13, and by its weight moves the lever 13 and the members 16, 20, 2 1 and 26 back to the 1n Fig. 2.

Flushing devices arranged according to position shown this invention may be made in many other ways than that described as an example, without departing from the spirit and scope of the invention. 'For instance the seat lid 8 may be connected to the stationary seat member 6 by common hinges, an d theanglelever 13 may be arranged on a special shaft secured to the stationary seat member 6. A' chaln or rope or the like may be substituted for the rod 16.

1V hen the lid has been bowl, said chamber having a supply cock.

and an outlet valve; :1 seat and a seat lid; and connecting means between the seat lid on one hand and the supply cook and the outlet valve on't-he other hand, said connecting means, when the seat lid is in its lowermost position, being actuated by the weightof the lid to open the outlet valve andei'lect the flushing, the supply cock being held closed and the outlet valve being open as long the lid remains in the lower most position, the connecting meansbetween the seat lid and the supply cock being adapted to be released from the lid when the latter is raised from its lowermost position to cut oil the supply cock, said connecting means also beingadapted to be automati-v with a float lever supporting member participating in the movement of the connecting means, said float lever supporting member also controlling the outlet valve and being adapted in its highest position, when the lid hasbeen laid down, to support the float carrying lever. of a float valve constituting the supply cock, so that the cock is held closed,rand at the'same time to hold the outlet. valve open, said float lever supportin inemberalso being adapted in its lowermost position, when the'lid has been raised, to allow the outlet valve to be closed and the float cock to be opened by the action of the weight of the float.

4,. water closet as claimed in claim 1, in which the seat lid is adapted to actuate the connecting meanslby an angle lever pivoted to thehinge shalt of the seat lid, one arm olisaid lever being adapted to be actuated by the seat lidwhen the latter has been laid down, while the other armis pivoted to the connecting means.

5. A water closet as claimed inclai'm 1, in which the connecting means consist of a rod pivoted 'at'its upper end to a lever pivoted to the hinge shaft, the lower end of said rod being pivotedtoan arm which is pivoted to the closet bowl;
